Question

An office building has 23 offices. The floor area of each office is 305 square feet. Which shows the equation you can use to find the floor area, n, of all the offices and the value of n?

23 + 305 = n, n= 810 square feet
23 x 305 = n, n = 1,405 square feet
23 x 305 = n, n = 1,425 square feet
23 x 305 = n, n= 7,015 square feet

Answer 1

To find the total floor area \( n \) of all the offices in the building, you would multiply the number of offices by the floor area of each office.

The correct equation would be:

\[
23 \times 305 = n
\]

Calculating that gives:

\[
n = 23 \times 305 = 7,015 \text{ square feet}
\]

So the correct choice is:

\[
23 \times 305 = n, \, n = 7,015 \text{ square feet}
\]
